whats the longest for ecstasy to kick in ?

I'm small and weigh 108 pounds. I took ecstasy last night at 9 called blue playstation. I was with a friend and she took it as well and felt everything. But I still haven't felt it yet and its the next morning. My pupils dialted but that's it. Please provide a lot of information. And when do you think it will kick in ? Or if it even will. Is it possible that It could have left my system without me feeling the effect ?
